I googled for Factory Method Design Pattern in Python but couldn’t find a good resource. So, I am sharing an example program to demonstrate this design pattern in Python which I frequently use. The factory method pattern is an object-oriented creational design pattern that deals with the problem of creating objects without specifying the exact […]

he Game of Life (or simply Life) is not a game in the conventional sense. There are no players, and no winning or losing. Once the “pieces” are placed in the starting position, the rules determine everything that happens later. Nevertheless, Life is full of surprises! In most cases, it is impossible to look at […]

n computer science, an AVL tree is a self-balancing binary search tree. It was the first such data structure to be invented. In an AVL tree, the heights of the two child subtrees of any node differ by at most one; if at any time they differ by more than one, rebalancing is done to […]

Binary search tree implementation in Python with: in, post and pre-order traversals. Also includes methods for insertion, deletion and search of nodes. Deletion is fairly complex and is made possible by keeping track of parents. A binary search tree (BST) or ordered binary tree is a node-based binary tree data structure which has the following […]

ython can implement the recursive formulation directly, caching return values. Memoization is a method where if a call is made more than once with the same arguments, and the result is returned directly from the cache. For example, we can dynamically solve the exponential Fibonacci series by using a Memoize class or a memoize function […]
